Letters Patent No. 90,750, dated Tu-nel 1, 1869.
\ IMPROVE!) FLOUR-SIFTER.
The Schedule referred to' in these' Letters Patent and making part of the name. l
dwd To all whomrit may concern/f` Be it known that I, E.' C. HICKMAN, of thecity and county of Washington, in the District of Columbia, have invented a newvand improved Sifter for Flour,
Cre.; and I'do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe saine, reference being had to the accompanying drawings, making a part of lthis specifica-tion, in which- My invention is represented by a longitudinal vertical section, takenI through the centre ofthe machine.
The object of this invention is to provide, for public use, a cheap and convenient device for sifting i'lonr, Src.
In the 'drawing- B represents the body or case of the sif'tcr, provided with a hinged cover, B', a drawer, D, and a hopper, H, having a sliding bottom, I. Within the box B is a smallerl box, C, having a sieve-bottom, E, and connected by a pitman, P, t-o the crank g, of a shaft, G, that is driven by a pininmn', and an internal gear-Wheel, M, having a crank, K.
This box slides rapidly back and forth on guides or ways, fw w, when the crank is turned, and sifts the flour, 85e., through the sieve E into the drawer D.
When necessary, the cover Br can be raised, the hook ofthe pitmau detached from the eye e, and the box C removed from the machine.-
The slide I serves to regulate the feed ol the flour, 85e., into the box C. Y
Having thus described iny`iuvention,
What I claim -as new, and desire to secure by Let ters Patent, is-
The device above described, consisting esscfntially of the box B, the drawer D, the reciprocating box C, having a sieve-bottom, E, the guides'w w, the detaehable'pitman P, the crank g, the shaft G, the wheels' m M, and crank K, the hinged cover B,tl1e hopper H, and the slide I, all constructed, arranged, and combined to operate in connection with each other, as and
